No discharge??

Emily • 😍 23 ❤️ 9 years with my love 😋 proud momma of a little boy 😄
So, idk which is normal, I used to have.. Well a rather large amount of discharge on a daily basis.. And now.. I haven't had any in two days.. Is that normal?? What could have changed that?? I had sex with me SO but we were protected. And I'm on birth control. So.. I really have no idea what's happening. PLEASE HELP!!
